C OMBING MACHINE.

Application filed August 26, 1924, Serial No. 734,345), and in Belgium September 1, 1923.

My invention relates to combing machines of the type comprising two stationary top combs and has for its object the provision of means for mounting the combs so that they operate in parallel planes, in the same direction and simultaneously, means being also employed for varying the distance between these parallel planes and this variation may be extended from the complete joining of the combs, to a suitable distance determined by the nature of the material. being treated.

The invention is applicable in connection with various constructions of combing machines and in the accompanying drawing,

' Figure 1 is a front elevation and Fig. 2 a

J side elevation of a frame carrying the top combs. Figs. 3 to 7 are diagrammatic views showing the application of this frame to a combing machine.

In appropriate bearings of the combing machine are mounted the trunnions 3 of an upper frame 1, which latter in turn receives the trunnions 4 of the lower frame 2, in such a manner that the two frames can move simultaneously and separately.

Each frame carries a stationary top comb, 5, 6, of different shape in order to permit of their reciprocal displacement. Because of the nature of the material. being treated a variable spacing must be provided between the combs 5 and (5, and the latter must present nearly the same inclination, so that the needles of the combs can be eventually joined. In the construction shown in the drawing, the spacing between the combs, 5, 6, is regulated by means of the screw's 7 and 8, whilst the regulation of the feed for the detaching rollers is obtained by means of the screws 9 and 10.

The regulation of the planes of the combs 5, 6 iseifected by means of the screws 11 and 12, acting on the lugs 13 of the combs.

In the diagrammatic view Figs. 3, 15 and 16 represent the detaching rollers with the drawing-01f leathers; 5 and 6 are the double stationary combs; above described; 17, the under nippers plate; 1.8 and 19 the nippers; 20, the gill box, with the feed comb and the grid; 21 is the circular comb.

In the position of the parts in Fig. 4:, the nippers being open, the feeding is effected by the gill box 20, the feed comb being closed. The gill advances till the end of the sliver comes between the detaching rollers, which begin rotating.

At this moment (Fig. 5). the two combs 5 and 6 fall together, and at the same time, the plate 17 moves forward and forces the iplaterial to enter deeply into the comb neec es.

I Vhen the detaching rollers 15, 16 have effected a certain movement of rotation, (Fig. 6) they are moved forwards so as to draw the sliver, which is finally separated from the combs. The sliver being combed, (Fig. 7) the end of th new sliver is separated from the stationary combs, 5, 6, which latter together with the plate 17 resume their initial positions, the nippers are closed and the end of the sliver is beat down and forced to enter into the bars of the circular comb 21. The end of the sliver being thus combed, the feeding gill 2O draws back, the nippers are again open, and a new feeding takes place as before described.

In order to clean and to regulate the combs, it is sufiicient to remove the upper frame 2, which is fixed to the machine by a spring applied at 14. Although the combs work together and are submitted to the same movements, they are independent of each other and this fact makes the cleaning and the regulation of the combs much easier than those in existing machines.

It results that the double stationary top combs work as a single comb, that is to say, in the same direction, and simultaneously in parallel planes and in combination with the detaching rollers.

The eiiiciency obtained by means of this double stationary top comb is superior to that given by means of a single stationary comb, as well in the treatment, by example, of wool containing thistles or not. In the second case, experiments have shown that the combing is more eflicient and complete, the cleanliness of the combed material is greatly increased and the waste proportion considerably reduced. In fact, by a suitable regulation of the space between the stationary combs, a deeper combing may be obtained, than by reducing the space between the detaching rollers and the nippers.

In the first case, by effecting a certain spacing between the stationary combs and by suitably spacing the detaching roller and the nipper, the thistles may be totally expelled from the combed material.

Having thus fully described the invention, What is claimed as new and desired to 5 be secured by Letters Patent is:

In a combing machine, two frames, a stat1onary top comb carried by each iranie, in such a manner that the spacing between the
